Moving Customer Defined Screens

I noticed an interesting phenomenon while moving a screen from LIVE to TEST. There was a difference in the queries between LIVE & TEST. I moved the LIVE version back to TEST overwriting the one in TEST. When I checked the screen in the TEST MIS Screen Dictionary, LIVE & TEST were now in synch. When I ran a report against the mis.screen.fields segment in the MIS.SCREEN dpm TEST did not match LIVE. After refiling the screen from TEST, they matched.

It would appear that it is necessary to refile a screen after it has been moved for changes to take affect when the move overwrites another screen in the destination directory.
